copy method

Future<num> copy(
  1. Reader src,
  2. Writer dst, [
  3. IInline1? options
])

Copies from src to dst until either EOF (null) is read from src or an error occurs. It resolves to the number of bytes copied or rejects with the first error encountered while copying.

Implementation

_i2.Future<_i2.num> copy(
  _i4.Reader src,
  _i4.Writer dst, [
  _i4.IInline1? options,
]) =>
    _i3.promiseToFuture(_i3.callMethod(
      this,
      'copy',
      [
        src,
        dst,
        options ?? _i6.undefined,
      ],
    ));
